That thought has occured to me from time to time as I've belted myself in my '70/4 with the very same belts. But I ask myself "How or where will they fail?"
The mounting points? The metal is solid there and the bolts clean and tight.
The webbing? Yes, it's old, but they've been kept clean and dry.
The buckle? It too is clean, dry and latches as it should.
I realize that this hardware is now 37 years old, but I'm inclined to think that if I'm in a "head-on" with a 3 ton Escalade while the ditz driving it is talking on her cell phone, the belts are beyond their capacity to save me from what will certainly be catastrophic sheetmetal failure and collapse.
I'd think that any collision force violent enough to cause belt failure would render survivability in such an incident unlikely anyhow
